Transition to Operations Review: LCLS-II Cryomodule Commissioning in LERF
November , 2018

2. Outline
LERF Setup and LCLS-II’s contribution Roles and Responsibilities in setup Main Objective for LCLS-II Additional Benefits Operation Support (or not)
A.Ratti, J. Schmerge, Transition to Operations Review: LSCL-II Cryomodule Commissioning in LERF

3. LCLS-II Setup at LERF
LCLS-II provided most of the electronics and control systems
SSAs
LLRF controllers
CryoModule controllers
These are all production units needed back at SLAC before the end of construction and the beginning of commissioning
JLAB contributed significant local support
Networking and Local Controls
All installation, cabling, RF power distribution, AC power….
All cryogenic system connections and interfaces
Funding to ship the equipment back to SLAC was allocated to JLAB
Relative roles and responsibilities described in a dedicated ICD
- LCLSII-2.7-IC-1116-R0

4. support cryomodule production testing and qualifications
Main Goals for LCLS-II
First and foremost
support cryomodule production testing and qualifications
expedite production and
help maintain an aggressive schedule

5. Other benefits to LCLS-II and its personnel
Testing and integration of all LCLS-II Electronics and Controls for two cryomodules
Similar setup to L1
Gain experience, complete integration
Learn CM testing with LCLS-II Hardware
Integrate cavity measurements and testing infrastructure in place at CMT* facilities

6. Operating the LERF setup
Funding from LCLS-II at SLAC does not include cavity/cryomodule testing and/or operations
Troubleshooting and Support for running the systems in LERF will come from SLAC on an as needed basis as part of the development of each subsystem involved
We are looking for funding to support training of SLAC staff in operating and testing SRF cavities and cryomodules
